Benefits of technology

The patent text describes energy delivery conduit connectors that can be used with medical device consoles that rely on either resistive or RFID-based identification of delivery conduits. The connectors have both a fixed resistance mechanism and an RFID tag, with the fixed mechanism at one end and the RFID tag at the other. A non-conducting over-nut separates the RFID tag from the fixed mechanism to prevent interference with the RFID tag's operation. This design prevents any duplication of delivery conduits related to identification. Overall, the technical effect of this patent is to ensure safe and reliable identification of energy delivery conduits in medical devices.

Problems solved by technology

A problem arises where both types of laser consoles (those using fixed resistance based identification and those using RFID-based identification) are in use.

Embodiment Construction

[0030]In the following description, various embodiments of the present invention will be described. For purposes of explanation, specific configurations and details are set forth in order to provide a thorough understanding of the embodiments. However, it will also be apparent to one skilled in the art that the present invention may be practiced without the specific details. Furthermore, well-known features may be omitted or simplified in order not to obscure the embodiment being described.

Electrical-Characteristic Based Identification

[0031]Referring now to the drawings, in which like reference numerals represent like parts throughout the several views, FIG. 1 shows a radiation source assembly 10 that employs electrical-characteristic based identification of a detachable delivery conduit 12. The delivery conduit 12 can be, for example, an optical fiber used to deliver radiation generated by a laser 14 to a patient tissue. The laser 14 and associated transport optics 16 are mounted t...

Abstract

An identification assembly for use with a fiber-optic connector includes a non-conducting over-nut, an electrical assembly disposed at the proximal end of the over-nut, and an RFID tag supported by the distal end of the over-nut. The over-nut is configured to surround and couple with the fiber-optic connector. The electrical assembly includes a first electrical contact configured to electrically connect to the fiber-optic connector, a second electrical contact configured for electrical engagement with a contact portion of a light source assembly, and one or more electrical components coupled between the first and second contacts and providing a defined electrical characteristic. The identification assembly enables identification using either electrical-characteristic based or RFID-based identification approaches.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application claims priority to Provisional U.S. Patent Application Ser. No. 61 / 704,799 filed Sep. 24, 2012, entitled “Hybrid Device Identifier,” the entire disclosure of which is hereby incorporated by reference, for all purposes, as if fully set forth herein.BACKGROUND[0002]Various medical devices deliver energy (e.g., radiation such as light, radio frequency, etc.) through a delivery conduit. For example, medical areas that use lasers include angioplasty, cancer diagnosis and treatment, cosmetic applications such as laser hair removal and tattoo removal, dermatology, lithotripsy, mammography, medical imaging, microscopy, ophthalmology (includes Lasik and laser photocoagulation), optical coherence tomography, prostatectomy, and surgery. Consoles used to generate the energy typically need to know what type of delivery conduit is attached for a variety of reasons (e.g., power attenuation, filtering, etc.).[0003]With many older laser d...
